Brief Summary
The aim of thid study was to compare two methods applied to increase the flexibility of the hamstring muscles and objectively evaluate changes in muscle stiffness using the two-dimensional shear wave ultrasound elastography (2D SWE) method. Thirty asymptomatic young individuals with hamstring shortness were divided into two groups by simple randomization. The Mulligan bent leg raise (BLR) technique was applied to the first group, and passive static stretching exercises to the second group. Hamstring flexibility was evaluated with the sit-and-reach test, and muscle stiffness with the 2D SWE method.

Outcome Measures
Primary Outcomes (1)
Back-saver sit-and-reach test
The difference between the back-saver sit-and-reach test and the classical sit-and-reach test is that the former is applied unilaterally. The test was administered using the sit-and-reach test box. The participants were asked to sit on a flat surface and rest the sole of one of their feet flat on the end of the box while keeping the other leg flat on the floor by flexing the knee and hips to 90° and 45° sequentially. Maintaining this position, they were asked to place one hand on the other with their palms facing down, slide their hands on the measuring board, slowly reach forward, wait for a second or two at the last point reached
Up to 2 months
Secondary Outcomes (1)
Two-dimensional Shear Wave Elastography
Up to 2 months
Study Arms (2)
Mulligan bent leg raise technique
EXPERIMENTALA single session of 3 repetitions of Mulligan bent leg raise was applied to the participants.
Static stretching exercise
EXPERIMENTALA single session of 5 repetitive stretching exercises was performed on the participants.
Interventions
In this study, while the participant was lying on his back on a high bed, the physiotherapist sat on the lateral side of the leg to be treated, placing the popliteal fossa of the participant's knee on his shoulder. The hip and knee of the leg to be stretched were placed in 90° flexion. Distraction was applied to the lower end of the femur, and the participant was asked to push the physiotherapist's shoulder with his leg and then relax. At this relaxation point, the physiotherapist pushed the flexed knee as far as possible in the direction of the ipsilateral shoulder in a painless range.
The participant lay on a stretcher in the supine position with his back straight. The physiotherapist placed the participant's leg on his shoulder with the knee in full extension and supported by the ankle and flexed the hip as much as possible until a tension was felt in the posterior thigh. This position was maintained for 30 seconds.
Eligibility Criteria
You may qualify if:
- Having a limitation of more than 25° in the active knee extension test
- Only engaged in recreational sports during the study period
- Having a history of lower extremity injury within the last two years
- Not volunteering to participate in the study.
